The statement is False,
The function and its inverse are reflected about the line y=x. This means that the x and y values are replaced.
So, if a function has a point (2,3) the same point on its inverse will moved be (3,2). This happens for all the points.
Therefore, the statement is false.
x² + bx - 81
there are 2 formula that fit this equation :
>> x² - a² = (x+a)(x-a)
or
>> x² + 2ax² + a² = (x+a)(x+a)
because the last value of our equation is negative value therefore we have to use the first formula >> x² - a² = (x+a)(x-a)
step:
x² + bx - 81
x² + bx - 9²
because we have to follow the first formula x² - a² therefore bx = 0
x² + bx - 9²
bx = 0
b = 0
Answer:
F(0) = 0
F(1) = 3
F(2) = 2 x F(1) + F(0) = 2 x 3 + 0 = 6
F(3) = 3 x F(2) + F(1) = 3 x 6 + 3 = 21
F(4) = 4 x F(3) + F(2) = 4 x 21 + 6 =90
F(5) = 5 x F(4) + F(3) = 5 x 90 + 21 = 471
Hope this helps!
